While I have shown my invention with respect to Watthour meters, it isnot so limited. but is applicable to various apph'caiions within thescope of the appended claims.

I claim as my invention:

1. An integrating device for a measuring instrument comprising a toothedescapement Wheel, indicators operatively connected to the escapementWheel, a spring adapted to move the escapement Wheel in one directiononly, and a grooved Wheel having a notch cut in each of its flanges onopposite radii thereof and adapted to be driven continuously in eitherdirection, said grooved Wheel being adapted to engage the teeth of theescapement Wheel and the notches being adapted to release the escapementWheel to actuate the indicators in one direction, irrespective of thedirection of movement of the grooved Wheel.

2. An integrating device for a measuring instrument comprising a toothedescapement Wheel tensioned to move in one direction only, indicatorsoperatively connected to the said Wheel, anda grooved Wheel having anotch cut in each of its flanges on opposite radii thereof and adaptedto be driven continuously in either direction by the measuringinstrument, the notches being adapted to release the escapement Wheel toactuate the indicators in one direction, irrespective of the directionof movement of the grooved Wheel.

3. An integrating mechanism comprising a toothed escapement Wheeltensioned to move in one direction only, an indicator operativelyconnected to the escapement Wheel, and a continuously operated Wheelhaving two flanges With notches cut therein on opposite radii thereof,said escapement Wheel being adapted to be released by the notchestensioned toothed escapement Wheel for engaging the same grooved Wheelat right angles, said escapement Wheel being permitted to turn in onedirection irrespective of the direction of rotation of the said groovedwheel.

5. An escapement mechanism comprising a toothed escapement Wheeltensioned to move in one direction, and a grooved Wheel having notchesout in its flanges on opposite radii thereof and adapted to movecontinuously in either direction, said grooved Wheel being adapted toengage the teeth of the escapement Wheel and the notches being adaptedto release the escapement Wheel in accordance with the speed of rotationof the grooved Wheel.

6-. A mechanism for a measuring instrument comprising an escapementWheel tensioned to move in one direction only, an indicator operativelycomiected to the escapement Wheel, and a continuously operated Wheelhaving tWo flanges provided With notches in its respective flanges onopposite radii thereof, said escapement Wheel being adapted to bereleased by the notches in the said flanged Wheel to actuate theindicator in one direction, irrespective of the direction of movement ofthe flanged Wheel.

In testimony whereof, I have hereunto subscribed my name this 16th dayof November, 1914.
